1976 Japanese TV commercial for the National Cougar 2200

1976 Japanese TV commercial for the National Cougar 2200 (aka Panasonic RF-2200 aka National Panasonic DR-22)

by 13dka

(The commercial starts at the 1:00 mark. It’s part of longer video with Japanese commercials from that year, there is a whole collection on YouTube if you like those!)

Doing some research on other old technical gems from Japan I stumbled upon this 1976 National/Panasonic TV commercial running on the domestic TV networks back then. While watching, I smiled and thought “only in Japan…” …it would’ve been perfectly normal to advertise something like a shortwave receiver in this fun (and funny) way. Anyway, I think RF/DR/Cougar 2200 owners and collectors (also the resident one on this blog , the blog owner) may want to have this link in their bookmarks!

Radio Waves: Stories Making Waves in the World of Radio

Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Paul, Dennis Dura, Richard Cuff, and Bake Timmons for the following tips:

Voice of America station in CNMI announces closure (Saipan Tribune)

The U.S. Agency for Global Media has announced that it will be closing its Robert E. Kamosa Transmitting Station in the CNMI after decades in operation.

The station broadcasts the Voice of America transmission to Asia.

In a letter form USAGM’s William S. Martin, director of operations and stations division, a big change is taking place at the U.S. Agency for Global Media’s Robert E. Kamosa Transmitting Station.

“The change is a discontinuation of all shortwave radio transmissions at our Saipan and Tinian sites, the first step in closing the station,” he said.

According to Martin, on June 26, the USAGM—an independent federal agency that oversees the Voice of America, Radio Free Asia, and other U.S. funded international civilian broadcasters—announced it was closing REKTS, its two shortwave radio transmission sites, on Saipan and Tinian.

[…]”While shortwave radio was an effective and popular way for people in media-deprived countries to access international news and information during WWII and the Cold War, Martin says shortwave use has fallen dramatically almost everywhere since the invention of the internet and the fall of Soviet Union in the 1990s.

WCBS 880 signing off after nearly 60 years, ESPN New York to take its place (lohud)

WCBS 880 AM, one of New York’s leading news radio channels for nearly 60 years, will be replaced with ESPN New York on Aug. 26, as 1010 WINS becomes the main radio station for real-time news coverage in the New York metro area.

Audacy, the parent company for both WCBS 880 and 1010 WINS, announced the agreement with Good Karma Brands, a sports media network, on Aug. 12. The station 880 AM will become the new home of ESPN New York and will use the call letters WHSQ-AM, pending FCC approval.[Continue reading…]

Hams Stepping up in Bangladesh (BBC Newsroom)

Many thanks to SWLing Post contributor, Bake Timmons, who writes:

Hams are stepping up right now in a very busy place — Dhaka, Bangladesh.

I heard ham radio mentioned this morning on this morning’s broadcast of the BBC program “The Newsroom”. A volunteer traffic coordinator and ham described (18:55 in the podcast linked below) how every traffic hub is now connected w/ amateur radio in the city of Dhaka, Bangladesh, in response to the absence of police, who have withdrawn from their normal duties after the ousting of prime minister Sheikh Hasina.

The First New Long Wave Radio Station Of This Millennium (Hackaday)

The decline of AM broadcast radio is a slow but inexorable process over much of the world, but for regions outside America there’s another parallel story happening a few hundred kilohertz further down the spectrum. The long wave band sits around the 200kHz mark and has traditionally carried national-level programming due to its increased range. Like AM it’s in decline due to competition from FM, digital, and online services, and one by one the stations that once crowded this band are going quiet. In the middle of all this it’s a surprise then to find a new long wave station in the works in the 2020s, bucking all contemporary broadcasting trends. Arctic 252 is based in Finland with programming intended to be heard across the Arctic region and aims to start testing in September. [Continue reading…]

A Nutty Idea

16 Replies

By Jock Elliott, KB2GOM

Official Disclaimer: “Yes, XHDATA is a supporter of the SWLing Post but this is my own crazy idea, and we aren’t getting any commissions from the sales. XHDATA doesn’t even know we’re doing it!”

It’s all Robert Gulley’s fault. He had the temerity to post an article about the XHDATA D-220 entitled “A Throwback to a Simpler Time” — I read it, was intrigued, and ordered one.

It arrived today, and, by golly, it actually works. I snapped a couple of AA cells into the battery compartment and discovered immediately that it appears to have a pretty hot FM receiver section. Then I tried medium wave and pulled up several of the local AMers. Then, the acid test: shortwave. Robert Gulley was right: “you will want to turn the dial slowly, very slowly.” But, sonuvagun, if you use a safecracker’s touch, you will actually discover and receive distant shortwave stations on that dinky telescoping whip antenna . . . with an exceedingly inexpensive radio.

So here’s my Nutty Idea: How about an XHDATA D-220 DX contest?

Rules:

You must use a D-220 with native antenna
No use of other radios or SDRs as “spotter” radios.
You must ID off the air.

As Thomas, our Maximum Leader, put it: “It’s so insanely cheap, it’s a great way to have everyone on a level playing field. Well, unless someone gets the yellow version which we all know has special powers.” (Yes, I bought the yellow version.)

Further, I proposed we kick this thing off at 6 pm your local time on Friday, August 16, 2024 and it ends at 6 pm your local time on Sunday, August 18, 2024. You log the time, the estimated frequency, the station ID and what you heard. There are no prizes, just bragging rights. The object: to have fun!

So, whaddya think?

Or should I go back to the home and start taking my meds?

Dale Recomends the Aziloop DF-72 Antenna System

Many thanks to SWLing Post contributor, Dale Parfitt, who writes:

I wanted to mention a receive only antenna that I am using at my home QTH. I do a lot of NDB logging during the winter below 500kHz, some AM band DXing and 160M. In the past I have had Beverages, homebrew Flag antennas, Shared Apex Loop Array and now last month I installed the new Quiet Radio AziLoop:

https://www.quietradio.co.uk/

With the Array Solutions Model AS-SAL, I could electrically rotate in 45 degree increments and also flip the direction by 180 or make it bidirectional. Click here to download the manual (PDF).

You can read the features of the AziLoop on Dave’s site. But the outstanding feature is rotating electrically every 5 degrees and 2 modes- small RX loop and K9AY. In K9AY mode I can achieve up to 30dB F/B and the rear null is very sharp. If it did not rotate in 5 degree increments, you would not even see the rear nulls.

But here is where it really stands out. The K9AY design, like the flags and Ewes, has a terminating resistance. By varying the value of that resistance via the AziLoop App, one can achieve skywave nulls. The value of that terminating resistance changes from day to night etc. So using that feature, I can often reduce co-channel or adjacent channel QRM or thunderstorm QRN. Small loops (aka magnetic loops) cannot do that. They are omnidirectional to skywaves.

Anyway, I mention this as some of your site readers both ham and SWL might find it interesting.

I built mine from telescoping fiberglass poles and it is completely standalone- no loops on the ground stakes etc.

I have no commercial relationship with Quiet Radio- just a very satisfied client.

Thank you for sharing this, Dale. I was not aware of the Aziloop. Fascinating!

Dan Robinson Reviews the New Tecsun S-2200X Portable Receiver

Many thanks to SWLing Post contributor and supporter, Dan Robinson, who shares the following review:

Tecsun Delivers The S-2200X – New Life For A 16-Year-Old Cabinet Design

by Dan Robinson

Note: Please see an addendum of updates at the end of this post.

Some months ago, I learned from Anon-co that Tecsun planned to release an update to the S-2000 receiver, which for the past 16 years also sold under other names such as the Grundig Satellit 750 and later the Eton Satellit 750 and Eton Elite 750.

To say that this radio was long in the tooth is an understatement.

I remember seeing one when they first came out back in 2008 and I was never very impressed. To me, the radio looked like a toy, and the performance did not impress. The standout feature was the top-mounted rotatable antenna for MW/LW reception. That was popular with those of us who own the Panasonic RF-2200 and it’s a great tool for MW.

Grundig Satellit 750

While popular with a certain segment of the listening hobby – beginners liked the 750 and even some veteran SWLs appreciated the retro design — the receiver was plagued by annoying issues, such as the famous wobbly tuning knob. It also had limited selectivity, no synchronous mode, and mediocre SSB.

In 2013, The Monitoring Times (Larry Van Horn) took another look at the radio with the following memorable comments:

[MONITORING TIMES 2013]

“Needless to say some folks were not happy with our review of the 750 including Etón. In retrospect, over four years later, I would not change one single word I wrote in that review. I believe we honestly gave a fair assessment of the unit that was shipped to us for review. If you read my previous review closely, you would see that most of my concerns back then had to do with quality control issues and most in our industry fully acknowledge that we were seeing some nasty stuff coming out of China back in 2008.”

So, measuring from 2008 when the first Eton 750 came out we’re now in 2024 and Tecsun has decided to preserve the cabinet design of the original radio while substantially upgrading the internals.

Enter the S-2200x

Reviewers have obtained units from the first production run. Tecsun has provided long-needed upgrades that put this radio on the same playing field as the very popular H-501 and PL-990 portables.

The 2200x adds a dedicated SYNC mode with its own front panel button. AIR band is retained, though sadly coverage doesn’t extend up to give us the NOAA WEATHER frequencies.

My initial testing of the S-2200x shows that performance is excellent on SW, AM, and FM. In contrast with portables from other manufacturers, SSB performance is excellent – in USB and LSB, tuning is smooth with no “warbling” and using the fine tuning control is a pleasure. Continue reading →

“Medium wave’s sunset in Europe”

Many thanks to SWLing Post contributor, Alan, who shares the following article from Red Tech:

Medium wave’s sunset in Europe (Red Tech)

GENEVA — European medium-wave transmitters are going silent. On April 1, the BBC shut down the nine transmitters that had previously brought BBC Radio 4 in AM to the whole country. Since January 2018, the British public broadcaster has started to switch off the AM transmitters for its local stations. Looking ahead, it plans to abandon the band totally by 2027 at the latest.

This trend goes beyond the BBC. In the last years, British commercial broadcasters have also switched off AM transmitters. In the case of Bauer Media, not a single AM transmitter remains operational.

The United Kingdom is the last fortress of AM transmission in Europe. Over the last 15 years, many other countries disconnected their last AM transmitters — Austria (in 2008), Switzerland (2010), Ireland (2012), Germany (2015), Belarus (2016), Albania (2017) and Belgium (2018), to name a few. More than 20 European countries have ceased AM transmission. Across the continent, less than 100 AM services remain active.

Notwithstanding, AM still resists against all odds in markets such as Estonia, Greece, Hungary, Poland, Portugal, Romania and Spain, among others. However, many big broadcasters still relying on this technology have often reduced their transmission power without receiving complaints from the audience. This is a strong signal about how the future may look like. [Continue reading…]
